Description:
A VITRIFIED PRODUCT CASTING MACHINE AND METHOD TECHNICAL FIELD

The present invention relates to a vitrified product casting machine and method where vitrified products can be produced by means of two-part mold. PRIOR ART

Today, in the castings of vitrified products like washbasin, shower tray, vitrified product casting machine is used having multiple mold system which pours pluralities of vitrified products onto a machine. However, in these vitrified product casting machines; in a casting process, only one type of vitrified product casting can be realized. The reason of this can be described as driving all of the hanger systems, where the female molds and male molds in vitrified product casting machine are connected, by means of a single motor. Since all of hanger systems are driven by means of a single motor, all of the hanger systems can rotate at the same angle and for instance, they stay at 90 degrees horizontally. By means of this, the vitrified products can be handled from the molds. In this case, only production of vitrified products which shall be handled from the mold at 90 degrees can be realized in such a vitrified product casting machine. For the vitrified products which shall be handled through other angles, a new vitrified product casting machine shall be provided. This leads to very serious monetary losses. Accordingly, the producer company shall produce single type of vitrified product, or if the producer company will produce different types of vitrified product, it shall face with big monetary difficulties.

The patent with number EP1958744 (A1 ) relates to a pressure die casting machine, in particular for manufacturing ceramic products, for example sanitary articles, comprising two mold holders suitable for receiving each a respective half mold. The mold holders are connected to respective support means reciprocally moving between a relative separation position, suitable for the demolding and drawing of the cast piece, and a relative approach position, wherein the two half molds are closed along a contact plane for casting and emptying the mold. The support means are in turn connected to orientation means suitable for orientating said support means so as to make said contact plane between the two half molds which can be turned by at least 90° between a substantially vertical position and a substantially horizontal position. As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

In this detailed description, the subject matter vitrified product casting machine (1 ) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

With reference to Figure 1 , 2, 3, and 4; the subject matter vitrified product casting machine (1 ) in general comprises a chassis (10), at least two rotary plate groups (20) connected to said chassis (10) and at least one movable foot (70) connected to said rotary plate group (20).

In the subject matter vitrified product casting machine (1 ), vitrified products can be produced by means of two-part mold (46) such that one is female mold (46) and one is male mold (46). These vitrified products may be washbasin, shower tray. Vitrified product casting machine (1 ) may comprise 2, 4, 6 or 8 of said rotary plate group (20) depending on the length of the chassis (10) and the desired production capacity. The rotary plate group (20) comprises a beam (22), two hanger arms (30) connected to said beam (22), at least two holder groups (36) and a rotary plate (44). The rotary plate group (20) is positioned in a manner sagging in axis y (Y) downwardly from the chassis (10) without having any connection with the floor. A connection arm (24) embodiment provides connection of the rotary plate group (20) to the chassis (10). Said connection arm (24) extends upwardly in axis y (Y) such that there is at least one each from each beam end (224) of a beam (22) embodiment of the rotary plate group (20). There is at least one assembly element (242) which provides connection of the connection arms (24) to the beam (22). Said assembly element (242) is preferably a bolt.

Said hanger arm (30) is positioned in a manner sagging in axis y (Y) downwardly from the beam end (224) without any connection to the floor. A hanger hole (306) provided at the upper end (302) parts of the hanger arm (30) is connected to a beam hole (228), positioned on the lateral surface (226) of the beam end (224), by means of a joining element (34). Said joining element (34) is preferably a bolt. In providing the connection of the hanger arm (30) to the beam (22), preferably pluralities of joining elements (34) are used. The hanger arm (30) is positioned in a manner sagging in axis y (Y) downwardly from the chassis (10) without any connection to the floor. There is a bracket (304) embodiment having a specific angle and which provides increasing of the distance of the two hanger arms (30), provided at the beam ends (224) of the rotary plate group (20) with respect to each other, at a specific amount as from under the upper end (302). Thanks to said bracket (304) embodiment, a movement gap (32) is defined between the two hanger arms (30) and the rotary plate (44) can realize rotation.

There is at least one holder group (36) connected to the lower end (308) of each hanger arm (30). Said holder group (36) in general comprises a connection plate (362) connected to the rotary plate (44) and a shaft (370) embodiment bedded with the rotary plate (44) with the help of a bearing (384). At least one plate fixation element (364) is used for providing fixation of the connection plate (362) to the rotary plate (44). Said plate fixation element (364) is preferably a bolt. The connection plates (362) grab the rotary plate (44) from both lateral edges (442) thereof. However, the rotary plate (44) is not positioned onto the floor in a manner parallel to the axis x (X) and it stays such that a part thereof is inclined towards the floor at a specific angle. Thanks to this angled position, the mud, which remains in the molds (46), can be discharged outwardly by means of a mud discharge unit (48) connected to a rotary plate (44). There is a body (38) part, connected to the holder group (36), between the hanger arm (30) and the rotary plate (44). There is a bearing house (382), wherein said bearing (384) is placed, on the body (38). Said shaft (370) is connected to a bearing body (366). Said bearing body (366) comprises a shaft bearing (368). The shaft (370) is placed to said bearing. The bearing body (366) is seated to the lower end (308) of the hanger arm (30).

There is a drive element (42) which provides movement of the rotary plate (44) and connected to only one of the hanger arms (30) provided in the rotary plate group (20). Said drive element (42) is preferably a motor. There is a reducer (422) connected to the drive element (42). The shaft (370) is connected to the drive element (42). While one end of the shaft (370) is connected to the rotary plate (44), another end thereof is connected to the drive element (42). The drive element (42) provides power transmission to the shaft (370) in order to provide rotation of the rotary plate (44) in the clockwise direction and in the counterclockwise direction as a rotation axis (E).

There is an encoder (45) connected electrically to the control unit (26) and which measures the rotation angle of the rotary plate (44).

Under normal conditions, while the female mold (46) is connected to a plate surface (444) of the rotary plate (44), the male mold (46) is connected to the other plate surface (444). When the weights of the connected female mold (46) and the male mold (46) are close to each other, the weight center of the rotary plate (44) is close to the rotation axis (E) of the shaft (370). Thus, by means of a smaller reducer (422), start and stop of the movement can be provided. When big and heavy molds (46) are connected to the rotary plate (44), in cases where the weight center diverges from the rotation axis (E) and where the rotational momentum required for rotation increases excessively such that said reducer (422) begins to face difficulty in rotating the rotary plate (44), a weight center balancer (40) is used as the system which provides relieving of the reducer (422). Thanks to the weight center balancer (40), the mold (46) can be rotated without needing to use a much greater reducer (422).

With reference to Figure 10, 1 1 , 12 and 13, there is the weight center balancer (40) connected to the body (38) and which provides the weight center to stay in said rotation axis (E) during the rotational movement of the rotary plate (44). The weight center balancer (40) essentially comprises a sliding structure (410) connected to the body (38) and a fixation wedge (402) and a stopper surface (408) which is preferably in C form, and an adjustment bolt (406). Said sliding structure (410) is an item which provides sliding of the rotary plate (44) in an orthogonal direction with respect to the rotation axis (E) of the shaft (370) and which is described as dovetail. In order to approach the weight center of the rotary plate (44) to the rotation axis (E), first of all, said fixation wedges (402) (there are one each fixation wedges at the front and at the rear) are loosened through said adjustment bolts (406). During loosening, in order to prevent uncontrolled movement of the connection part (404), the adjustment bolts (406) are contacted to the connection part (404). Afterwards, the adjustment bolts (406) are tightened in the weight center balancing direction. As the adjustment bolts (406) are tightened, the connection part (404) is slid on the body (38) thanks to the sliding structure (410). After some sliding, the fixation wedges (402) are tightened and the rotary plate (44) is rotated by means of reducer (422). Said adjustment is continued until a comfortable rotation is obtained by means of reducer (422). When a comfortable rotation is obtained both in the clockwise direction and in the counter-clockwise direction, the fixation wedges (402) and the adjustment bolts (406) are tightened and the adjustment process is completed. Thanks to the inclined surfaces of the fixation wedges (402), the fixation wedges (402) are tightened in their housings, and they prevent deterioration and loosening of the adjustment.

The rotary plate (44) is preferably made of aluminum material. One each molds (46) can be connected onto both plate surfaces (444) of the rotary plate (44). While a female mold (46) is connected onto a plate surface (444) of the rotary plate (44), the male mold (46) is connected onto the other plate surface (444). There is a cocoon (446) embodiment in slit-like form on the plate surfaces (444) of the rotary plate (44). By means of said cocoon (446), the molds (46), which are in different dimensions, can be connected to the rotary plate (44). There are preferably pluralities of cocoons (446) on the plate surface (444), preferably on the rotary plate (44).

In the vitrified product casting machine (1 ), in the pluralities of rotary plate groups (20) provided side by side, the plate surfaces (444) of the rotary plates (44), where each female mold (46) and each male mold (46) are connected, are parallel to each other. By means of this, in order for the rotary plate group (20) to be tightened and to be casted, the male mold (46) of a first rotary plate group (B) and the female mold (46) of a second rotary plate group (20) are connected to each other.

In a similar manner, the female mold (46) of a first rotary plate group (B) and the male mold (46) of a second rotary plate group (20) can be connected to each other. In other words, the male mold (46) or the female mold (46) can be connected to the desired plate surface (444) of the rotary plate (44). In order to realize vitrified product casting, the important factor is to mutually correlate a female mold (46) and a male mold (46) on the plate surfaces (444) of the rotary plates (44) facing each other.

There is a control unit (26) which controls operation of the rotary plate group (20). Said control unit (26) is preferably connected to the upper surface (222) of the beam (22). The control unit (26) can be connected to the beam (22) by using at least one fixation element (262). Preferably by using pluralities of fixation elements (262), the control unit (26) can be positioned to the upper surface (222) of the beam (22) in a rigid manner. There is at least one motor (28) connected to the rotary plate group (20) and which provides movement of the rotary plate group (20) in axis x (X) horizontally along the chassis (10). Said motor (28) is preferably a double shaft torque motor (28). The motor (28) is connected to the upper surface (222) of the beam (22). Thanks to the usage of the torque motor, high level of torque at lower revolutions can be generated. Besides, space saving is provided. The control of the torque motor is easy and it operates with cheap drivers. There is no oil ingredient in torque motors; they are electric motors (28). Since torque motors do not include oil, the risk of oil dropping is completely eliminated.

There are one each control units (26) which separately belong to each rotary plate group (20) which is provided in the vitrified product casting machine (1 ). Additionally, each rotary plate group (20) has separate one each drive elements (42). Thus, the movement of each rotary plate group (20) can be controlled in an independent manner from each other. As a result, each rotary plate group (20) can act as if it was one each separate machine. Since the rotary plate groups (20) are independent from each other, each rotary plate (44) can be rotated at different angles and at different directions and can be stopped at the desired angle and direction. Separate commands are given from the own control units (26) of each of the rotary plate groups (20) and the rotary plates (44) can be rotated at a predetermined angle range and can be stopped at these angles and the vitrified products can be handled. The angle range is preferably between +90 degrees and -90 degrees. By means of this, in each rotary plate group (20) provided in the vitrified product casting machine (1 ), vitrified products with different models and characteristics can be casted.

With reference to Figure 19, there is a main control unit (60) where all of the control units (26), which belong particularly to each of the rotary plate groups (20), are connected. Said main control unit (60) controls the movements of the rotary plate groups (20) horizontally in axis x (X) in the processes during casting and after casting. Besides, the main control unit (60) controls the control units (26) of the rotary plate groups (20) and provides the coordination in between.

There is at least one movable foot (70) embodiment provided in the vitrified product casting machine (1 ) and which provides interconnection of the female molds (46) and the male molds (46) by tightening the rotary plate groups (20) in order to realize casting. Said movable foot (70) is preferably connected both to the chassis (10) and to the machine base (80). In an alternative embodiment, the movable foot (70) can only be connected to the chassis (10). The movable foot (70) tightens the rotary plate groups (20) in an accordion manner for realizing casting. After the casting process, the female molds (46) and the male molds (46) are diverged from each other and they facilitate diverging of rotary plate groups (20) from each other in order to provide handling of the casted vitrified product.

The details of a subject matter vitrified product casting machine (1 ) have been given above, and the operation method of the machine is as follows:

There are eight rotary plate groups (20) connected to the chassis (10) in the vitrified product casting machine (1 ). With reference to Figure 18, the vitrified product casting machine (1 ) method essentially comprises three steps of the mold binding step (K), the casting step (D) and vitrified product handling step (V):

Mold binding step (K): With reference to Figure 16 and 17, first of all, the rotary plate groups (20) are positioned in axis y (Y) orthogonally and such that there is a specific distance in between. The female molds (46) and the male molds (46) are connected to the plate surfaces (444) of the rotary plate groups (20) by using cocoon (446) embodiment. The mold (46) is connected only to the plate surface (444) of the first rotary plate group (B) facing the second plate group. In a similar manner, the mold (46) is connected to the plate surface (444) facing the rotary plate group (20), which is the one just before the last, for a last rotary plate group (S). Molds (46) are connected to both plate surfaces (444) of the other rotary plate group (20) which remains between said first rotary plate group (B) and said last plate group. Casting step (D): The movable foot (70) moves in axis x (X) horizontally in order to begin tightening the rotary plate groups (20). Here, the object is to connect the female molds (46) and the male molds (46), provided at rotary plates (44), to each other and make them ready for casting. After the molds (46) in the rotary plate groups (20) are completely connected to each other, by means of the command given by the main control unit (60), mud begins to completely fill the volume between all female and male molds (46) engaged to each other. After the filling process is completed, in order for the mud to gain thickness in the mold (46), it is waited for a while in this manner.

Vitrified product handling step (V): When the vitrified product becomes ready to be handled from the molds (46) after gaining thickness, the movable foot (70) is activated by means of the command from the main control unit (60), and in order to diverge the molds (46) from each other, the movable foot (70) begins moving in the opposite direction from the tightening direction. Together with the movable foot (70), the rotary plate groups (20) also begin movement. After the molds (46) are separated, they stay at a distance which will provide the rotary plates (44) to be able to realize rotations at required angles for the vitrified product handling. This distance can be basically determined by taking into account the dimensions where the rotary plates (44) do not have contact with each other when the rotary plates (44) are positioned so as to be parallel to the floor in axis x (X). Afterwards, the movable foot (70) stops its movement and it is fixed at its location.

Since each rotary plate group (20) has a unique control unit (26), each of the rotary plate groups (20) acts as if it was a separate machine, and the amount of rotation which shall be realized with respect to the angle of handling the vitrified product for the rotary plates (44) in the rotary plate group (20) can be adjusted in a separate manner. If the vitrified product shall be handled through the female mold (46) because of the structure of the vitrified product, the rotary plate (44) rotates and stops so as to provide handling of the vitrified product from the female mold (46) at a suitable angle. In a similar manner, if the vitrified product shall be handled through the male mold (46) in accordance with the structure of the vitrified product, the rotary plate (44) rotates at a suitable angle and stops so as to provide handling of the vitrified product form the male mold (46). Vitrified products can be handled simultaneously from all rotary plate groups (20). In handling of vitrified products from the related mold (46) in each rotary plate group (20), preferably a product handling vehicle (90) is used. After the rotary plate (44) stops at a suitable angle, said product handling vehicle (90) is brought to a region which is close to the molds (46) in order to provide handling from the molds (46). Afterwards, the vitrified products can be handled. Some vitrified products shall be handled from the mold (46) in an orthogonal manner to horizontal axis x (X) in accordance with the nature of these vitrified products . In this case, optionally, product handling vehicles (90) can be parked near the vitrified product casting machine (1 ) and since the rotary plate group (20) is orthogonal, an operator intervenes in between and said operator can handle the vitrified product and can place the vitrified product in the product handling vehicle (90). The independency of each rotary plate (44) from each other provides advantage.

The protection scope of the present invention is set forth in the annexed Claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
